****ty customer service and *****ulent back end staff

I have had the most disgusting service from this company. Did early cancelation on both my contracts with them. Got the quotes, signed paid and submitted everything as requested. I got confirmation of the calculations and 2 days later got told my cancelations were canceled. After repeated back and forth I got told it was canceled. Then last week I got 2 calls from MBD attorneys who said my account was in arrears. These contracts were canceled in July 2025. How in God's name am I sitting with an arrears of over 3000 when I paid the cancelations in full. I demand an explanation and they don't even have the decency to respond to the countless emails if sent. ****** pathetic company and ****ty no existent support. I've ported my number to telkom so I can't even call in to get help
